Tamiya 94739 JR 19mm Blue Roller Upgrade

The Tamiya 94739 JR 19mm Aluminum Ball Race Roller is a limited edition component aimed at racers who want both function and style. The blue anodized finish sits on a light aluminum body and the included 520 ball bearings deliver smooth, reliable rotation for cleaner lines on the track.

Fitment, Parts Included and Benefits

These rollers are suitable for Mini 4WD and Mini 4WD PRO chassis, providing a flexible upgrade choice. The set comes with screws, 520 ball bearings, rubber rings and aluminum spacers to ensure a complete fit. Use them to tighten handling or to add a race-ready visual touch to your car.

How do these compare to plastic rollers?

Aluminum rollers are stiffer and typically offer smoother rotation with less deformation under load, which helps maintain consistent racing lines versus plastic units.

Is the blue anodize durable?

The anodized layer provides corrosion resistance and a durable surface finish, though normal wear can occur with heavy track contact.

Can I replace the bearings later?

Yes, the rollers use standard 520 bearings which can be swapped if you choose to upgrade to sealed or higher quality bearings down the line.

Do these need maintenance?

Periodic cleaning and light lubrication of the bearings will keep rotation smooth and extend component life, especially after dusty or muddy runs.
